ASharing pairs of electrons
BLosing pairs of electrons
CGaining pairs of protons
DTrading pairs of neutrons
Answer & Solution
Correct answer: A. Sharing pairs of electrons
1. Atoms bond in order to fill their outermost energy level, as the noble gases already have.
2. A covalent bond is a chemical bond where pairs of electrons are shared between two atoms.
3. The outermost orbitals overlap so that unpaired electrons from each atom can be shared.
4. Protons and neutrons sit in the nucleus and take no part in ordinary bonding.
